Which one has the greatest mass?
1. 3.55 mol o atoms
2. 4.52 g o atoms
3. 0.0032 kg o2 molec
4. 7.39 × 1023 o2 molec

The correct answer is Option 1.

Explanation:

For the given options:

To calculate the number of moles, we use the equation:

Moles of Oxygen = 3.55 mol

Molar mass of Oxygen = 16 g/mol

Putting values in above equation, we get:

Mass of oxygen atoms = 56.8 g

Mass of oxygen atoms = 4.52 g

Converting this into grams, we use the conversion factor:

1 kg = 1000 g

So, 0.0032 kg = 3.2 g

Mass of molecule = 3.2 g

According to mole concept:

1 mole of an atom contains number of atoms.

If, number of atoms occupies 32 grams of oxygen molecule.

So, number of atoms will occupy =

Mass of molecule = 39.2 g

Hence, the greatest mass is coming out from option 1.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
